That rather suggests that this 'gap seal' does not just block the gap
with
the flaps up but improves the airflow over the flap though the gap when
the
flaps are down.
Is there a picture of it anywhere?
Regards
Pete

Flaps down...

Are you talking about landing flap up or flap down?

Jeff,
Why does the tape need to be so wide, or does it just come in 2 1/4"
widths?
If you get a chance, perhaps you could publish a photo.
Best wishes,
William

Last year, I had the pleasure of flying into John's airstrip, in
Tennessee
and visiting with him and his near finished bird, for a while. In our
conversation, John mentioned how sealing up the aircraft would clean up
the lines, resulting in better speeds. As John said, the glider guys do
it and it works. Well, while I had Baby Blue disassembled and was
cleaning her up for Sun-N-Fun (which she did not make, as she was still
ailing from the weak carb spring incident) I decided to add some gap
seals
to the wing, to seal the flaps, upon retraction. What I used was a
2.25"
wide piece of .020" styrene, a product that I use, almost daily in my
sign/graphics business. I attached it to the wing using 1" hem tape (a
very strong, two sided tape, used to hem banners). Once the engine was
restored to normal operating condition, the results were immediate and
astounding. I haven't done a complete test, yet, but the results seems
to
have yielded about 4-5 kph at cruise. It has also resulted in more
float,
during landing, which I attribute to reduced stall speeds. I say
reduced
stall speeds, because, by reducing my final approach from 65 kph to 60
kph, across the numbers, Baby Blue lands like she used to. I'll be
doing
more extensive tests, as the weather settles. However, I am extremely
pleased with the initial results of the simple and inexpensive mod.
Thanks again, John for your suggestion...
